The `Schedule :eferred to in these Letters Patent and making part of the same.

To all whom it ma/y concern:

Be it known that I, PHINEAS D WEssoN, ofthe city and county of Providence, and State of Rhode Island, have invented-a certain new and useful Steam- Heater.

The prominent feature of my invention consists in a novel arrangement of pipes and chambers, which, as a whole, constitutes a new and improved apparatusffor heating by steam.

To enable persons skilled in the art to make and use my invention, I do hereby declare the following sp'eeication, taken in connection with drawings furnished as a part of the4 same, to be a full, clear, and exact description thereof'. n

Figure l represents an elevation view of my heaters, complete.

Figure 2 represents a View of the same, in longitudinal section. l A is an inner chamber, into which steam is introduced at point C.

A A- are steam-pipes, the lower ends of which are tapped into chamber A. The upper ends are open.

B is thechamber, to Whichfthe discharge-pipe is attached at point D.

B B are the radiating-chambers, closed at the upper.

end, and tapped into the chamber B at the'lower end.

C, point of induction.

D, discharge-pipe connection.

Figure 3i exhibits, in cross-section, chambers Aand B, pipes A A, and chambers B B.

rJJhe operation of my heater is obvious. The steam, entering at C into chamber A, courses upward through the pipes A A, as indicated by thearrow in the drawings, reverberates against the inside of thetop of chambers B B, then downward into chamber B, topass the outlet at D.

Steam-heaters have here tofore been constructed in a variety of wa'ys, the general object being to present upon their exteriors as much radiating-surface as possible. Pipes and chambers have been used in their construction, with a variety of 'diierence in their arrangement. In n'one of vthose heretofore constructed, however, has the arrangement of pipes and chambers been such as would cause thesteam to proceed directly and at the-same time to all the most distant points of the interior of the heater. On the contrary, lthe steam,

upon entering, connes in all nooks and recesses such air as they chance to contain, owing to an obviously deficient circulating power.

Some have been arranged in which steam coursed` up and down or back and forth through pipes, connected at the ends, alternately. In such heaters, the steam must follow thecourse of the pipes, length by length.

In--my new heater, the action of the steam is uniform and rapid. The pipes the farthest from the induction are practically as warm, and capable at all times of furnishing as much heat as those nearest thereto.

Having thus explained my invention,

I claim asynew, and desire to secure by Letters Patent- A steam-heater, composed of the outer and inner chambers A and B, the radiating-chambers A A, and the pipes B B, relatively arranged and operatingsubstantially as shown and described, for the purposes speciied. y
